Anybody know how to repair a non-ADB keyboard? The "R" key on my keyboard unfortunately does not work. I'm trying to use drakar's NeXT-to-USB adapter, and it works great except for this silly "R" key issue.

I ordered some two years ago with the intention to build my own mechanical keyboard design (but never found enough time to design it) - so if anyone needs a single keyswitch, let me know (I'm located in Germany, so sending the switches overseas probably won't make too much sense).

If it's not something mechanically broken with your keyswitch, I guess chances are good that - as long as you are able to de solder it - you can open and clean it with some dedicate product and restore its functionality by gently tweaking the leaf spring.
I did it today on some Alps switches from an old Apple IIe, from dead key to fully functional in a couple of hours.
